log_{10}(a^2-15a)=2

lo g_{10} (a^{2} - 15 a) = 2

a = 20, a = - 5

Solution steps

lo g_{10} (a^{2} - 15 a) = 2

Apply log rules

a^{2} - 15 a = 100

Solve

a^{2} - 15 a = 100 : a = 20, a = - 5

a = 20, a = - 5

lo g_{x} (\frac{1}{4}) = - 2

ln (x^{3} - 3) = 3 ln (x) - ln (3)

- lo g_{10} (x) = 4

lo g_{2} (x - 6) + lo g_{2} (x + 1) = 3

lo g_{5} (x - 8) = 1 - lo g_{5} (x - 4)
